Title: Improvements in or relating to origin-discriminating call systems
Inventor: GRIFFITHS CHRISTOPHER ALAN
IPC: G08B3/10
Filed: 1968-09-06
Abstract: 1278584 Electric selective signalling PLESSEY CO Ltd 1 Dec 1969 [6 Sept 1968] 42543/68 Heading H4K and 12B An origin discriminating electric call system comprises at each of a number of calling stations 3, a switch arranged to produce in a common line circuit 2 to a discriminating receiver, station 1, a distinctive pulse which produces at the receiver station a distinctive indicator response in order to identify the origin of the signal. The system may be used in a hospital, the stations 3 comprising wards each provided with a lamp 4 which lights up when a call is made by a patient operating the switch in a bedside unit 8. A corresponding lamp 5 at the receiver station lights up to identify the ward making the call and a loud-speaker 6 emits a kHz. tone for 300 milliseconds. A nurse answering the call may operate an emergency switch in the unit 8 which overrides any ordinary nurse calls in that ward to cause intermittent operation of the corresponding lamp 5 and the loud-speaker 6. The station 1 produces interrogation pulses at a frequency of 10 Hz. and each ward station 3 is able to reply to these pulses with a call pulse having a time spacing with respect to the interrogation pulse which is characteristic of the ward station. On operation of the switch in the unit 8 the call pulses are fed to a channel decoder in the station 1 which identifies the ward making the call by switching on the corresponding lamp 5 and the loud-speaker.

Title: Improvements in or relating to devices for securing self-adhesive labels
IPC: B65C1/00
Filed: 1969-08-27
Abstract: 1,223,204. Labelling device. METO-GESELLSCHAFT OSCAR KIND m.b.H. 27 Aug., 1969 [3 Sept., 1968], No. 42649/69. Heading B8F. A device for securing self adhesive labels to articles comprises a deflection edge 8 for forwarding the labels with the adhesive layer turned upwards from a label carrier belt 2 to a 1  label lifter 3. A goods carrier 5 situated above the label lifter 3 has an opening 4 through which the label is pressed against the bottom of the article 6 when the label lifter meets the carrier. The carrier belt 2 is pulled intermittantly by a draw-off device 7 through a guide channel 65 and over the deflection edge 8 where each label is removed individually and is forwarded to a flexible pad 10 of the label lifter 3. In one embodiment the goods carrier 5 is pressed manually downwardly against a spring 12 to actuate the label lifter 3 and retract the draw off-device 7 via levers 42 and 17 respectively. The carrier belt is clamped by a clamp 28 and the article 6 is labelled by upward motion of the label lifter. Downward movement of the carrier also actuates a roller 70 by way of levers 77, 75 to draw a loop of the carrier belt from a supply spool. The belt 2 is pulled over the deflection device 8 by a predetermined amount so as to forward another label 1 to the label lifter 3 as the carrier 5 returns to its starting position. In a further embodiment, the goods carrier may be part of a shoot such that when an article is forwarded to the carrier, downward motion of the carrier actuates electromagnetic drives for the label lifter and carrier belt.

The invention comprises penicillins of Formula (I) and non-toxic salts thereof, wherein R and R 1  are the same or different and each is a phenyl or thienyl group, X is H, NH 2 , or -NHCOOR<SP>2</SP> where R<SP>2</SP> is alkyl, aryl or aralkyl, and Y is H, NH 2 , -NHCOOR<SP>2</SP> (as above), or -NH COR<SP>3</SP> wherein R<SP>3</SP> is H, alkyl, aryl or aralkyl. Typical compounds are 6-[D-α-(L-#-amino-#- phenyl - propionamido) - α - phenylacetamido] - penicillanic acid (A) and 6-[D-α-(D-α-amino-#- phenylpropionamido) - α - phenylacetamido] - penicillanic acid (B). The penicillins are produced by reacting an α-amino penicillin of Formula (II) or a non-toxic salt thereof, with a propionic acid derivative acylating agent of formula wherein Z is a functional group for acylating primary amines; L is H, -NHCOOR<SP>2</SP> (as above) or other N-protected amino group; and M is H, »NHCOOR<SP>2</SP> (as above), -NHCOR<SP>3</SP> (as above) or other N-protected amino group, to form a penicillin of Formula IX) wherein R, R<SP>1</SP>, L and M have the above meaning, and if the penicillin of Formula (IX) does not fall within the definition of Formula (I), or if it is desired to have X or Y in Formula (I) as an NH 2  group, the additional step of converting the N-protected amino group L or M in the penicillin of Formula (IX) to an amino group. Catalytic hydrogenation is used to convert N-protected amino groups in the form of azido, benzyloxycarbonyl amino and subsubstituted benzyloxycarbonyl amino. Mild hydrolysis is used to convert N-protected aminogroups in the form of enamine groups of general Formula (VI) or tautomeric modifications thereof, i.e. wherein the dotted lines represent H bonds, and R<SP>1</SP> is C 1-6  alkyl, R<SP>2</SP> is H or together with R<SP>1</SP> completes a carbocyclic ring, and R<SP>3</SP> is C 1-6  alkyl, aryl or C 1-6  alkoxy; Z represents the residue of a substituted or unsubstituted benzene or naphthalene ring. Penicillin (A) may be prepared as above or by reacting 6 - D - [α - amino - α - phenyl acetamido] - penicillanic acid with an acylating derivative of L - N - (1 - methoxycarbonylpropen - 2 - yl) - #-amino-#-phenylpropionic acid. Sodium L - N - (1 - methoxycarbonylpropen - 2 - yl) - # - amino - # - phenyl propionate is produced by treating sodium L-#-amino-#- phenyl propionate with methyl acetoacetate. D - α - ethoxycarbonylamino - # - phenyl propionic acid is produced by reacting D-α-amino- #-phenyl propionic acid with ethyl chloroformate.
